The red colour usually allows you to spot it from a distance: iron ore. The volcanic rock is mainly used in the manufacture of steel. India has vast reserves of iron ore and is the second-biggest steel producer in the world. The deployment of quality mobile screening plants can provide big productivity and efficiency gains during the extraction of this vitally important material.
India’s total iron ore production for 2019 was 231 million tons, around 90% of which was used in domestic steel production. Hematite and magnetite are the iron ores mainly found in India. Thanks to its high quality and lumpy properties, hematite is the most sought-after iron ore for the local steel industry. Due to its fine grain properties, the processing method of the sedimentary rock usually demands a lot from the screens. This is where premium classifying screens such as Kleemann’s MOBISCREEN EVO units provide a valuable service.
In an open-pit iron ore site in Keonjhar in the federal state of Orissa, Kalinga Commercial Corporation (KCC) is responsible for iron ore extraction on behalf of the state-owned company Orissa Mining Corporation. Since January 2020, KCC has deployed six MOBISCREEN EVO mobile screening plants from Kleemann to produce consistent, high-quality, and sized final iron ore products.
Working alongside KCC’s Kleemann screening models are more than 20 excavators handling and loading the iron ore. A fleet of 140 large dumper trucks transports the material from the open-pit site for further processing by the screening plants.
Five double-deck MOBISCREEN MS 952 EVO screening plants and a triple-deck MS 953 EVO screening plant classify the blasted and then crushed material into up to three or four required fractions (within a 0-10mm and 10-40mm range). KCC has achieved a daily production target of 30,000 tons in a two-shift operation with these six mobile classifying screens. The MOBISCREEN MS EVO screening plants operate precisely and efficiently under extreme conditions. In KCC’s Keonjhar open-pit iron ore site they process feed material with a humidity content of 6 – 7 % without any problems.
Dr. S.R. Samal, managing director, Kalinga Commercial Corporation, said: “We have been using Kleemann screening plants for more than two years. These plants have proved their value regarding product quality and output. Over the years, they have become an indispensable element of our operation. The service, above all, is exemplary. The co-operation with the Wirtgen Group was crowned with success. The investment was worthwhile because we managed to achieve our goals within the defined period.”
EVO series screeners impress with their high productivity, good transport properties and first-class screen results. The series includes the two double-deck classifying screens MS 702 EVO and MS 952 EVO, and the triple-deck classifying screens MS 703 EVO and MS 953 EVO. High production outputs combined with effective screening of up to four first-class final products can be achieved thanks to the models’ generous 7 or 9.5m² screening surfaces.
Depending on the application case, throughputs of up to 350 tonnes/hour (MS 702 and MS 703 EVO) or 500 tonnes/hour (MS 952 and MS 953 EVO) are possible.
Safety features are another key part of Kleemann’s MOBISCREEN EVO screening plants. They can be operated conveniently with an intuitive control system via a mobile control panel that can be attached at three different points. This increases work and operational safety. Thanks to the easily accessible work platforms, service activities can be carried out quickly, and screen surfaces can be efficiently replaced. All other service components can be accessed from the ground.
